I love the more detailed analysis but I'm overwhelmed. 

There is still money down required but helps ease costs

But nowadays pvc or pex is an easier fix.

All residents but the smokers have lost use of their balconies and keep windows closed now.

But it is definitely worth asking.

Companies normally offer limits up to$500,000 but some offer $1,000,000.

You still claim the income as miscellaneous income and deduct property taxes and mortgage interest (subject to SALT and other high mortgage limitations) on your Schedule A, but that's it.2. 

There are a lot of people in the city but I find other cities more warm for connections / networking.

Some may have very small thresholds for repair holdbacks on purchases but this is typically limited to make ready items not to exceed $2,500 in costs to cure.

A partnership requires three things to be successful - Experience, Capital and Time.It looks like you have the capital and experience but maybe not the time.I have my doubts about this working if you have a friend who has weak credit and a limited cash flow.
